To all whom it may concern:

Be it known that I, Tnoams G. PLANT, a citizen of the United States,residing at Boston, in the county of Sulfolk and State of Massachusetts,have invented an Improve ment in Laying and Leveling Machines,- of whichthe following description, in connection with the accompanying drawings,is a specification, like numerals on the drawings representing likeparts. I

The invention to be hereinafter described relates tosole laying andleveling machines and more. particularly to the boot or shoe support andits actuating means.

The aims and objects of the present in vention are to provide a boot orshoe support and actuating means of improved construction, moreespecially with reference to the purposes of a sole laying or levelingmachine, although, as will be evident, features of the present inventionare adapted for use in other relations.

The objects sought by the present inventid will best be understood byreference to th following description and accompanying drawings ofv oneform of meansfor carrying the invention into practical effect, it beingunderstood that the invention in its true scope is not restricted to thedetails herein, but is definitely set forth by the claims.

In the drawings: Figure 1 is a front view of a solelaying or levelingmachine embodying the present invention, said machine in its entiretybeing preferably formed in duplicate or as a twin machine, only one ofwhich is shown; Fig. 2 is an enlarged section on the line 2-2, Fig. 1;Fig. 3 is a detached detail side View of the shoe support, partsbeingbroken away to disclose structures beyond; Fig. 4 is a detached andenlarged plan View of the shifting cam, parts being shown in section;Fig.- 5 is a detail View of that part of the shoe support directlysustaining the shoe, some of the parts being broken away; Fig. 6 is adetail of the jacking slide rod for actuating the last-pin; Fig. 7 is afront View of the" lower portion of the parts shown by Fig. 5, lookingin the direction of the arrow, Fig. 5; Fig. 8 shows in side View thedetails of the size adjusting means; Fig. 9 is a detail sectional viewof the loose last-pin on the line 9-9, Fig. :1; F ig. 10 is a top Viewwith parts shown in section of the heel stop and counter clamps and viewin detail, showing the means for auto matica lly actuating the counterclamps, some of the parts being omitted; Fig. 12 isa section on the line12-12, Fig. 11, showing-also the counter clamp slides or carriers; Fig.13

is a section on the line 13-13, Fig. 10; Fig-- l-i is an enlarged detailshowing the toe and instep support, some of the parts being in section;Fig. 15 is a detached detail view showing the instep support;and Fig. 16is an enlarged view of the cam for automatically actuating the shoesupport or jack during the operation of the machine.

Referring to Figs. 1 and 2 of the accompanying drawings, the machineframe may be of any suitable or desired character for sustaining theoperating parts, and, as illustrated, comprises uprights 1 connectcdattop and bottom by suitable cross tics 2 and 3, substantially asdescribed in my prior application Ser. No. 454,082, filed September 21,1908. Extending between the cross ties 2 and 3, or from the top to thebottom of the machine frame, are the tie rods 4; suitably connected tothe machine frame at top and bottom by nuts 6 screw-threaded thereto. Asin my prior application the machine frame may be formed in duplicate soas to afford suitable sustaining means for duplicate mechanism or, ascommonly-understood,

a twin machine; and the tie rods 4 may, as in said application,constitute guiding means for a table 7 which is adapted to slidevertically on said rods, said table affording a suitable support for.the shoe supporting means or jack, to be hereinafter described.

Mounted on a fulcrum 8, Fig. 2, is a lever 9 connected at 10 to'a yoke11 from which rises a rod 12 having a nut 13 on its upper end above thescrew-threaded adjusting device 14 through which it passes, a spring 15being interposed between the yoke 11 and a collar 16 connected to theadjusting device 1% and adapted to be rotated by means of a handle 17 orother suitable means, all substantially as in my prior applicationreferred to, the construction being such that upon actuation of thelever 9 by any suitable means the table 7 to which the adjusting device14 is connected, as in said application,

will be suitably raised and lowered, as will be clearly understood.

Mounted in suitable bearings in the machine frame 1 is the main drivingshaft 18 having a fast and loose pulley 19 and 20 thereon, Fig. 1, saiddriving shaft being suitably connected to the clutch shaft 21 providedwith clutching and unclutghing devices, substantially as in my saidprior application, and said devices being therein fully described needno further description here. ()peratively connected to the clutch shaft21, as in my said prior application, is a cam faced gear 22 mounted onthe cam shaft 23 and which, when the clutching devices are manipulatedto cause the machine to operate, will be rotated at suitable speed, aspointed out in said application, to eii'ect the desired operations to tohereinafter described. The cam faced gear 22 carries on one face thereofa suitable cam 24' for acting upon a roll 25, Fig. 2, on the lever 9whereby, as said cam faced gear 22 is rotated, the lever 9 will beraised and lowered in response to the cam 24. Suitably mounted to slidelaterally on the table 7 is a cam plate 26, Figs. 1, 2 and 4, said camplate being sustained on said table by means of suitable sustaining webs27, 2 and 4, and, aside from the peculiar formation of its cam path 28,Fig. 4, said cam plate 26 may be substantially as set forth in my priorapplication herembefore mentioned. As in my before mentionedapplication, the cam plate 26 is designed to be given a lateral ortransverse vibratory movement, and to this end there is mounted on thetable 7 the bell crank levers 29, as in said prior application, saidbell crank levers being suitably connected, as indicated in Fig. 4, tothe underportion of the cam plate 26, and the free arms of said leversbeing joined together by a. connecting or tie rod 30, Figs. 2 and 4, theconstruction beingsueh that upon movement of the rod 30 the bell cranklevers will' be vibrated to give transverse or lateral movement to thecam plate, in a manner substantially as pointed outin my priorapplication.

Extending from the rod 30, Fig. 2, is a lug 31 carrying a threadedsleeve 32 pivotally connected thereto at 33 and engaged by ascrew-threaded rod 34, having a hand wheel 35 at one end and connectedat its opposite end'at 36 to the upper end of a lever 37 pivoted at 38to the machine frame or a bracket extended therefrom, said lever beingjointed at 39, Fig. 2, to an actuating rod 40, the

- rearlend of which is adjustably mounted in the slot 41 of a linkmember 42, pivoted at 43 and having a part engaging the cam groove 44 ofthe actuating cam 45, substantially as pointbd out in my priorapplication, with the exception that in said application no provisionwas made for changing the path of lateral or transverse vibration of thecam plate, whereas in the present invention means are provided to thisend, such means being embodied as one form of the invention in theadjusting rod 34 having screw-thread connection with the arm 30,whereby, Without altering the amplitude of ceases transverse or lateralvibration of the cam plate, its path of vibration may be changed. In thepresent embodiment of the invention the adjusting rod 34 has also ascrew-thread connection 46', Fig.- 2, to athreaded sleeve 47 whichafiords connection with the lever 37, said screw thread46 preferablybeing of a different pitch from that of the screwthread connectionbetween the rod 34 and the sleeve 32. However, so far as the broad scopeof the invention is concerned, these details may be variously changed,the improved feature in this respect being the capacity for changingthepath of lateral vibration of the cam plate 26 while still maintainingits original amplitude of Vibration.

In order to change theamplitude of vibration given to the cam plate 26,the cam faced gear 22 is provided with a cam 48, Fig. 2 adapted toengage aroll or pin 49 carrie by a lever 50 pivoted at 51. and having anodset port-ion 52 through which extends an adjusting screw 53 having ahand adjusting wheel 54, said adjusting screw being connected to a. pinor block 55 movable in a slot 56 of said lever and jointed to the upperportion of a lever 57, the lower end of which is connected at 58 to alifting lever 59 pivoted at 60 and havin its other end con-.

nected at 61 to a lin 62 which is itself jointed to a link 63connectedto the end of the rod 40, the construction being such that upon rotationof the cam faced gear 22 the cam 48 will move the lever 50 and, throughthe connecting devices, move the end of the rod40 in the slot 41 of thelink member 42, thereby .varying the extent of movement given to saidrod 40 and consequently, through. the connecting mechanism hereinbeforedescribed, changing the amplitude of lateral or transverse movement ofthe cam plate 26.

It is desirable on different portions of the shoe sole to effectdifferent treatments in a sole laying and leveling machine, as pointedout in my prior application, and the cam 48- carried by the cam facedgear 22 is so formed that the proper or desired treatment on any part ofthe shoe sole may be had through the instrumentalities hereinbeforedescribed, it being evident that the shape of the cam may beappropriately varied to suit varying purposes in this regard. As anothermeans for varying the character of the transverse movement given to thecam plate 26, the adjusting screw 53 may be manipulated by the handwheel 54 to move the end of the lever 57 nearer to the or farther fromthe fulcrum 51 of the lever 50, all as will be readily understood.

lilaving reference to Fig. 1 of the drawings there is shown herein asole laying or leveling'device constituted as a mold havingsubstantially the same general contour as the sole of the shoe to betreated. This mold 64 may be substantially the same as that shown anddescribed in my prior application referred to and may be suitably actuated to bring corresponding portions of the mold 64 and shoesole intocoacting relation by, means of the gears 65 and 66, the latter beingsecured't'o an upright shaft 67 having a gear 68 "for operativeengagement with suitable teeth 69, Fig. 3, on the jack carriage orcarrier, to be hereinafter described. The form 64 may also be given alongitudinal vibratory movement through the gear connection shownbetween the shaft 70, Fig. 1, and the vibrating means for said 'form,which may be substantially the same as that shown and described in myprior application, and, since such form and its actuating means are notto be herein claimed, further elucidation thereof will be unnecessarlllounted in suitable guideways 71 and 72 of the table 7 and so-astomove longitudinally of said table is the jack carrier or carriage 73,Figs. 1, 2 and 3, the connection betweenthe said-jack carrier and tablebeing substantially the same as that set forth in my prior application.

In order that the jack carrier 73 may be properly moved longitudinallyof the table the hand wheel 82 the length by the former, such 7.in theguideways thereon, that is, toward the front and rear of the machine,the rear portion of said jack carrier'is connected to a pitman 74pivoted to the jack carrier at 75, and at 76-connected to the upper endof an actuator 77 which is mounted at its lower end on a shaft 78 andhas connected to its hub an operating arm 79, Fig. 2, said arm beingshown in dotted lines.

jwhich reference will hereinafter, be made.

The pitman- 74 connecting the jack carrier wlth its actuator 77 ispreferably provided with means for adjusting the len 11 thereof,

as, for instance, with ahand whee 82, Fig. 2 with the right and lefthand screw-thread connection 83, 83, to the parts of the pitman, as willbe readily understood, the construction being such that uponmanipulation of of the pitman 74 may beiengthened or shortened.

The jack carrier 73, Figs. 1, 2 and 3, has rising from its-base portionthe supporting arms 84, one at either end, which constitute thesustaining means for a cradle 85 carrying the shoe support element. theconnec tion between the ack carrier 73 and cradle 85 being such as toprovide for shifting the supports of the cradle laterally relative 'tothe direction ofthe application of pressure line of support beingaccomplished without The upper end of the arm '79 is provided with aroller or lateral shifting of the.

substantially tilting oiswinging the table and being susceptible ofcontrol, so that equal pressures may be applied to the sole at each sideof its center at any point in its length, or such pressure may be causedto act more effectively on one side than on the other side. As one meansof carrying this feature of the invention into effect, the cradle 85 isprovided at either end with a supporting top portion or head 86, 86which rests upon a slide 87, Fig. 3, which is mounted to movetransversely of the jack carrier and which may be pivotally connected toanother slide 88 as at 89, said slide 88being also mounted on the jackcarrier 7 3 ,to move transversely. The slide 88 is .preferably supportedon a track 90,. and to secure ease of movement transverselyanti-friction devices may be interposed between the two, as likewisemaysuch anti-friction devices be interposed between the head 86 and theslide 87, substantially as set forth in my application hereinbeforereferred to and as also fully described in my prior application Ser. No.415,835, filed February 14, 1908.

In order that the cradle 85 may be held from pivotal movementtransversely of the jack carrier when its supports are movedtransversely, a plate 91. Fig.3, is secured to the jack carrier andprovided with a suit-, able projection 92 to engagea correspondingrecess fornied in the head'portion of the cradle, all substantially aspointed out in my prior application 415,835, to'which ref erence' hasbeen made.

From the above description and fromthe more detailed description in mysaid prior applicatiomit will be clear'that any pressure applied to ashoe sole supported on the jack or shoe support will be transmittedthrough the heads 86 of the cradle (one of said heads of course being ateither end of the cradle) to the jack carrier 73 through the pins ortrunnions 89 and at the line connectnig these pins or trunnions whichconstitutes the line of support for the jack. This line of support ispreferably, though not necessarily, in the general horizontal plane ofthe last bottom. so that the support for the last is substantiallv inthe .plane thereof. The shifting of this line of support laterally ortransversely with reference to the jack and the shoe mounted thereon isherein accomplished by shifting the slides 88 relative to both the jackcarrier 73 and the cradle 85. thus carrying the terminals of the line ofsupport ofthc pins'to one or the other side of the central line of theshoe or the line along which the pressure is applied. The means foreffecting this shifting movement. of the line of support may besubstantially the same as that set forth in my said application 454,082,and comprises a lever 93 piw otallv mounted at each end of thejackcarrier 73 at 94, the upper end of which works a. assess in a recessformed in the slide 88. If, now, the lower ends of these levers be movedtransversely, it will be a parent that the line of su port will beshifted laterally or transverse y with respect to the jack and the shoemounted thereon. In order to effect this shifting action of the line ofsupport, the lower ends of the levers 93 are appropriately under thecontrol of the cam path 28 in thecam plate 26, it being understod thatany suitable means for connecting the lower ends of these leversoperatively wlth the cam path 28 may be employed. In the presentillustration of the invention the means is substantially the same asthat shown and described in my prior application 454,082 and comprises aroller 95, Fig. 3, mounted on a suitable pin 96 carried by a slide 97movable transversely of the jack carrier and sustained by a slotted web98, the slide 97 havinga recess appropriately engaged by the lower end99' of the lever 93, it being understood that substantially the sameconnecting means between both of the levers 93 and the cam path 28 maybe employed. The rolls 95, moving in the cam path 28 of the cam plate 26as i the jack carrier is moved back and forth in response to itsactuating means, will have imparted thereto lateral movement in responseto the formation of the cam path 28, as will be readily understood.Likewise, any transverse or lateral vibration given to the cam plate 26will be likewise imparted through the rolls 95 to the levers 93. Thusthe line of support will be shifted in accordance with thecharacteristic of the cam path 28 and also in accordance with anylateral movement of the cam plate 26.

Mounted in suitable ways 100 in the cradle 85, see Fig. 7, is the shoesupporting saddle or jack proper 101, Figs. 5 and 7. Rising from therear portion of this shoe supporting saddle or jack proper 101 is thepost 102, Figs. 3, 5 and 9, and pivotally mounted at 103 in the post 102is the last pin support 104, having the last pin 105, the lower end ofsaid last pin support, Fig. 5, being connected at 106 to an upwardlyprojecting arm 107, Figs 5 and 6, rising from an actuating link 108,said actuating link 108 being preferably formed as a yielding mcmberand, in the present embodiment of the invention, comprising two parts,Fig. 6, connected by an adjustin bolt 109 having nuts 110 on one endthereoi and bearing against the outer portion of one end member, and theother end being screw-threaded at 1.11 into the other member, a spring112 being intcr mscd between the two members, substantially as indicatedin Fig. 6, whereby, upon movement of the actuating link 108 rearwardlyby pressure upon the front member, the last pin support will be turnedwith a yielding movement to jack the shoe, as will be readilyunderstood.

As indicated in Fig. 9, the last pm support 101 is loosely pivoted tothe post 102 that it may have lateral or transverse movement withrespect to said post, as indicated in Fig. 9, the eflect being that thelastpin 105 and its support may readily accommodate themselves to thevarying positions of the last pin receiving recess 118 in the lasts.

As well known by those skilled in the art, shoe lasts are formed withthe last pin receiving recess 118 and an attempt is made to haveuniformity in their location, but, as a matter of fact, they vary verymuch in different lasts and even in lasts of the same size, andespecially is this variation in location marked in the transverseposition of the last pin receiving recess. The importance of the loosepivotal connection of the'last pin support will be readily appreciatedfrom the above fact taken in connection with the fact that the heel orrear portion of the last must seat itself against the heel gage and alsobe uniformly embraced by the counter clamps, all of which willhereinafter more fully appear.

Pivotally mounted on the shoe supporting saddle or jack proper at 11 1,Figs. 5 and 7, is the jacking lever 115 having loosely mounted thereon acrank-arm 116, said crank arm being operatively joined to the jackinglever by means of a spring 117, Fig. 7, one

end of which is secured to the jacking lever at 118 and the other end ofwhich 1s connected at 119 to the crank arm 116, the hub of said crankarm being provided with a stop 120 and the shaft 114 being provided witha pin 121 to limit relative movement of the crank arm 116 in response tothe spring 117.

Extending transversely near the bottom of the post 102 is a shaft 122having an cecentric portion 123 carrying a jack. lock 12% providedwith'teeth 125 which are adapted to engage complemental teeth 126 fixedto the bottom portion of the cradle 85, as clearly indicated in Figs. 5and 7. The shaft 122 has a crank arm 127 which is connected to the crankarm 116 by means of link 128, the construction being such that uponmovement of the jacking lever contra-clockwise, Fig. 5, the crank arm116, through the s ring 117, will move in a like direction an turn theshaft 122, so that if the teeth 125 and 126 on the jack lock and cradlerespectively are engaged, the eccentricity of the jack lock umunting,with respect to the-shaft 122, will give a backward sliding movement tothe shoe supporting saddle after the shoe has been seated against theheel gage, as will hereinafter more fully appear, and will maintain theparts in this locked position. The jack lock 12 1 is provided with afinger 129 which rests upon a pin 130 connected to the jacking levercontra-clockwise the pin 133 will move in said slot and force theactuating link 108,- rearward, thereby turning the last pin support 104with a yielding motion upon its fulcrum 103, and jack the shoe, in amanner well understood.

Pivotally supported at 134, Fig. 3, on the cradle 85 is a heel gagelever 135 having an upwardly extending ortion 136 against which bearsthe end 0 an adjusting screw 137 carried by a lever 138, said adjustingscrew and arm 136 being held in engagement by a suitable spring, as 139.Supported on the-upper portion of the lever 138 is the heel or back gage140, Figs. 3, 10, 12 and 13, preferably faced with a yielding or othersuitable material 141 to contact with the rear portion of a shoe, whenthe latter is placed in operative position.

The toe rest 142:-;"F1gs. 3 and 5, is preferably mounted for ad ustmentupon a carrier 143 secured to a toe rest support 144 which may besubstantially as set forth in my applieation 429,202, filed April 25,1908. The

toe restsupportis pivoted at 145 to the shoe supportingsaddle 101 andprovided at its upper portion with slots 146 into which extend the pins147 carrying the toe rest, said pins being sustained upon s ringsupported. plungers 148, substantially as set forth in my application429,202, means such as the rack teeth 149 and 150, Fig. 14, beingprovided, as more fully set forth in the application just referred to,for locking the toe rest in position of -adjustment as the shoe movesthe toe rest into conformity with itself and as the shoe is jacked, allas set forth inmy prior application. In the pres ent case a spring 151connected to tile depending arm; 152 and to a fixed part 153 tends tonormally hold the toe rest in position for the most favorable engagementwith the toe of the shoe, an adjusting screw 154 serving to limit themovement of the toe restin response to the spring 151.

In order to effect size'adjustment, that is,

Q to adjust the toe rest and heel gage relatively to accommodate theparticular-size of shoe to be treated, the toe rest support 144, Fig. 8,is provided with an arm 155 having .a pin 156 in engagement with a block157 movable in a slideway 158 formed in a bearing 159 carried by a pm160, the construction being such that upon vertical movement of the pin160 the toe rest will be swung on its pivotal support 145 tocarry ittoward or 'link 163; said hand lever being ing saddle is secured or fromthe heel gage, as will be readily understood. To effect such movement ofthe gage, a size adjustment device is employed, comprising a hand lever161 pivoted at 162 and connected to the heel gage lever 135 by alikewise conpin 160, as indicated in Fig. 8, and as fully set forth inmy prior applicat1on429,202-, so that upon movement of the lever 161 theheel and toe gages will be appropriately moved. lnasmuch as the size adusting means, comprising the trip catch 164, Fig. 8, its hand operatingdevice 165 and associated parts, are similar to those of my priorapplication 429,202, it will be unnecessary to herein further describethe nected to the I same.

Pivotally supported on the toe rest support 144 and preferably on thepivotal axis 147 of the toe rest is an instep support, Figs. 2, 3, 5 and14. In the present form of the invention, with respect to this feature,the instep support comprises suitable side plates 166, Figs..5 and 14,carried by the cross pin 147 and suitably joined together to form arigid structure by the web 167 Fig.14. The lower portion of one of theinstep supporting plates is formed as a segment 168, Fig. 14, andprovided with a series of holding teeth 169, said teeth being adapted toengage a spring-pressed pawl 170 disposed be low the same, saidspring-pressed pawl being preferabl devices in or er to get fineradjustment, as will be readily understood. Obviously, va-

rious means might be employed to hold the instep support in its adjustedposition, other than the toothed segment 168 and the springholding'pawls 170, but the present devices are found in practice to bewell suited to the purpose, although not essential to this feature ofthe invention. The instep support is provided with bearings 171, 171,suitable for supporting a shifting pin 172 to which is connected aninstep supporting saddle 173, Fig. 15, said saddle being preferablyprovided with a set screw 174by which to connect it to the shifting pin172, Fig. 15. The sleeve 175 to which the instep supportby which it iscarried has a depending lug 176, Fig. 15, and

a spring 177 has one end connected to said lug and the other end to afixed part of the instep support, as at 178, Fig. 14, the constructionbeing such that the spring 177 nor-' mally tends to maintain theinstep'supporting saddle to one side of the instep support, as indicatedin Fig. 15. The instep supporting saddles 173. are preferably formed inpairs, one for rights and'one for lefts, in order to accommodate thedifferent swings of shoes, as will be readily understood. For

instance, the instep supporting saddle shown formed as a series of such'by Fig. 15 would be adapted for one swing or form of shoe, and a saddlehaving the reverse formation, that is with the right side more extendedand elevated than the left, would be adapted for shoes having anopposite swing, as will be readily understood by those skilled in theart. As will also be obvious, when one form of saddle is substituted foranother, the spring 177 may be suitably changed to position the instepsupporting saddle on the proper side of the instep support suitable tothe swing of the shoe to be supported. With respect to the instepsupporting means, also, various changes may be made in the details andformation of parts within the true scope of the invention, the eneralcharacteristics of such support being indicated in Fig.- 1 1, whereinthe dash and dot line represents approximately the outline of a shoeinstep and the relation thereof to the instep supporting saddle when inthe act of engagement therewith. It will also be noted that the instepsupporting saddle may accommodate itself rotatively in the bearings 171so as to readily conform to the contour of the shoe instep.

The axial support. 147 of the instep supporting saddle has securedthereto a handle 179, Figs. 3 and 5, whereby it may be swung up intoshoe engaging position and there held by the toothed rack 168 and itscooperating pawls 170.

It will be noted that the instep support is movable toward and from theheel or back gage 140 with the toe rest, and it will be also noted thatthe holding pawls 170 are spring actuated so that after the shoe hasbeen acked and its toe firmly seated in the toe rest, at which time therack teeth 169 are engaged with the spring pawls' 170, the instepsupport may be adjusted by the hamdle 17 9 so as to force it firmly upinto con-' tact with the instep of the shoe, the petals 170, at suchtimes, yielding to the passage of the teeth 169, Fig. 14;.

In order that the lasted shoe may be securely held in operative positionduring the action of the laying or leveling means on the sole thereof,it is desirable that the counter of a shoe be engaged and held bysuitable counter clamps. As t' shoe is jacked and moved back against theheel rest 1 10, it is desirable that the counter clamps be separated sothat the rear of the shoe can readily move to place, and that thereafterand prior to the action of the leveling means upon the sole, the counterclamps be firmly placed against the counter of the shoe. Having thesematters in mind, the present invention contemplates automatically actingcounter clamps to secure the above objects and as one embodiment ofmeans to this end the following is of good practical form.

The heel gage supporting lever, preferably Sat its upper portion, seeFigs. 3, 10, 12 and 18, is provided with a suitable guideway 180 inwhich move the slides 181 and 182 carrying counter clamps 183 and 184:respectively, Figs. 8 and 10.

Mounted to turn in suitable bearings carried by a bracket 185, Figs. 3and 10, is a shaft 186 having a right and left screw thread 187, Fig.12, said right and left screw threads engaging correspondingly threadedportions 188 and 189 of the slides 181 and 182 respectively, as clearlyindicated in Fig. 12, the construction being such that upon rotativemovement of the shaft 186 the slides 181 and 182 and perforce theircounter clamps are moved toward and from each other.

In the particular embodiment of the invention herein illustrated, theshaft 186 is surrounded by a sleeve 190', Fig. 12, which is supported inthe bearings 191 carried by the bracket 185, said sleeve being providedwith a suitable collar 192 and connected to rotate with said shaft 186.The outer end of the shaft 186 is screw-threaded and is engaged by aclamping nut and collar 193, the latter bearing against the exterior endof the sleeve 190. Splined to the sleeve 190 is a hand wheel. 19% havingconnected thereto a gear 195 whereby, by rotative movement of the handwheel or gear, the sleeve 190 and perforce the shaft 186 will be comespondingly rotated.

Pivotally mounted upon the cradle 85 as at 196, Fig. 11, is an arm 197carrying a segment gear 198, the teeth of wliiclnywhen the parts are inposition indicated inl ig'. 10, are in operative engagement with theteeth of the gear 195, and extending from the pivotal support 196 ofsaid arm 197 is a finger 199, to the lower end of which is connected oneend of a spring 200, the opposite end being connected at 201 to a fixedpoint on the cradle 85, the normal tendency, of said spring being tomove the finger 199 to the left, Fig. 11, until it contacts with thestop pin 202, as will be clearly apparent from Fig. 11.

From the construction described it will be obvious that upon movement ofthe rack segment 198 the shaft 186 will be turned Pivotally mounted uponthe table 7, Fig.

11, as at 203, is a segment actuator 204 comprising an arm extendingrearward of the table 7. Secured to the ack carrier 73 is a cam piece205 disposed so as to engage the curved'portion 206 of the segmentactuator as the said jack carrier moves outward to its full position forremoval of the shoe from drop from the cam piece 205, thereby permittingthe spring 200 to turn the rack segment 198 and close thecounter clamps.The relative disposition of the cam piece 205 and segment actuator 1ssuch that the segment actuator 204 will not be raised into position toengage the end of the finger 199 when the jack carrier is moved towardand from the front of the machine during the laying or levelinoperation, butis so moved when the jack carrier is given its fullforward movement to present the jack for removal of a shoe or theplacing of a shoe thereon.

It is sometimes desirable that the counter clamps be moved or adjustedby hand, and to enable this. to be done conveniently the presentinvention contemplates means for turning the shaft 186 at .desired timeswithout moving the segment 198, such means in the present form .of theinvention comprising a sliding connection between the hand wheel 194 andgear 195 and the sleeve 190, such connection being preferably formed bya spline 208, the construction being such that the hand wheel 194andgear 195 may be moved toward.the end ofthe shaft 186 to disengage thegear 195 from the segment rack 198, and, as the hand wheel and gearstill remain in splined connection with the shaft 186, said shaft may beturned in either direction, as desired, inclependent of movement of therack segment 198. As a means for maintaining the hand wheel 194 andgear195 in position, as indi cated in Fig. 12, with the gear 195 inengagement with the segment rack 198, a spring-pressed plunger 209 isprovided, Fig. 12, said plunger having a rounded inner end, asindicated, adapted to engage a suitable recess in the sleeve 190 whenthe gear 195 is in position of engagement with the rack segment, theconstruction being such that, upon a forceful pull of the hand wheel 194and gear 195 toward the end of the shaft 186, the plunger 2p9 will yieldand permit movement of the parts toward the end of the shaft, as will beapparent. Then the proper adjustment has been made, the parts may bereturned to initial position and there held by the plunger-209 with thegear 195 in engagement with the rack segment 198.

From the construction described it will be apparent that, when the jackproper or shoe supporting saddle is pulled to the front, the

jack carrier. at such times being in position as indicated in Fig. 2,and the jacking lever 115 in position as indicated in Fig. 5,'- a lastedshoe may be readily applied to the last pin and the'toe ofthe shoe besupported on the toe rest, the counterclamps at such timahaving beenseparated by the segment actuator 204 in the manner hereinbeforedescribed. \Vith the shoe and parts in position as indicated in Fig. 5,,the heel.

gage and toe rest having manipulated forsize adjustment,. if the shoesupporting saddle be moved backward to bring the'rear of the lasted shoein 0011 tact with the heel gage and the jackinglever 115 thrown to the'.left, the jack lock will have its teeth 125 engaged with the teeth 126on the cradle and as the jacking lever is given its full throw to theleft, the ecoem -tricity of the jack lock 124 with respect-to the shaft122 will give a final backward pressure to the shoe supporting saddleto" bring the rear of the shoe in firm contactwith the back gage. Withthe parts in this position, the instep support maybe mani'p fulated bythe handle ,179 to throw the in-. step supporting saddle into firmcontact with the instep of the shoe. Upon starting :the

machine.into operation in the mannerset' forth in my previousapplication 454,082,

the jack carrier will be moved backward,

thus disengaging the finger 199 from the segment. actuator 204 I andpermitting the spring 200 to actuate the counter clamps and force themin firm contact with the shoe;

As hereinbefore indicated, the l'ast' pinsocket in the last may be outof line with the central portion of the last and if means were notprovided, the uniform complement'al motion given the respective counterclamps would cause the counter clamps to 'bear unequally upon oppositesides ofthe shoe, but, owing to the loose lateral play afforded the lastpin support 104, the lasted shoe is permitted to center itself withrespect to the counter clamps and thus be held in firm and fixedposition, regardless of the position latorally of the last pin socket inthe last.

\Vhenthe jack; carrier has been moved to the rear to bringthe sole ofthe shoe into position with a part of the shoe sole beneath the laying'or leveling form, the table 7 is.

appropriately raised through the means.

hereinbcforc described, causing the form and shoe sole to be broughtinto contact atthe shank of the latter, the cam plate 26, at such times,being transversely vibrated to vary the relative position ofuthe line ofsupport with respect tothe jackor shoe sole. Owing to the character ofthe cam path 81 in the cam faced gear 22,- the jack carrier movescontinuously backward until the laying or leveling form meets the toe ofthe shoe, the cam path 28 in the camplate 26being such as to provide thenecessary variations in "pressure on different port ons of. the shoeforth a short distance to treat the toe of the shoe, there being littleor no transverse vibratory shifting of the line of support with respectto the shoe at this time. The cam 81 then moves the jack forwardly sothat the form travels over the sole from the toe to the rear of theshank, and as itpasses or just as it has passed from the ball of theshoe, the plate 26, under direction of the cam 48, again'commcnces tovibrate transversely as before, and the jack carrier is then moved totravel the form toward the ball line of the sole, finally returning sothat the form rests on the shank of the shoe as at the beginningof theoperation, such movement of the ack carrier being caused by the cam path81, and the cam plate still continuing its transversevibration. Thisoperation is'then repeated in treating a Welt shoe, and when the jackcarrier has been moved to its initial position at the commencement ofthe operation, it drops under the'direction of the cam 24 and lever 9,and then moves to the front to a position of presentation.

In some Work, as in solo laying, it is desirable that the aboveoperations be not repeated, the form, in such cases, moving only onceover the sole either with or without vibrative movement of the cam plate26; and in turn Work the same operation as first set forth may becarried out, except that the repeat at the toe is or may be avoided, ifdesired, such modifications in the operation of the machine being due tothe particular form of cams employed.
